(Cl. 248-49) through a cable extending along the rod to the surface.v

The cables are located in the well intermediate the rod and aV lining tube and are subject to being damaged during the insertion of the rod and during a pumping operation. i

It is one object of the present invention to overcome the disadvantages of the known holding means for holding alcablegsuspended in a deep well, and to provide a cable holding device which can be easily attached and detached.

With this object in view the present invention mainly consists of acable holding device for use with a rod projecting into a deepV bore and including coupling sleeves forming transverse annular shoulders on the rod. The cable holding device according to the present invention is preferably protected against corrosion and comprises, in combination, a cable holding member having at least one cableV bending edge and attaching means secured to the cable holding member and adapted to attach the same to the rod in a position in which the bending edge forms a knee in a cable located between the cable holding member and the rod.

The cable holding device according to the present invention bends two portions of the cable when attached to the probing rod so that the bent cable portions abut on the Vannular shoulders of a coupling sleeve preventing movement of the cable in longitudinal direction of the rod, and supporting the weight of the cable.

The invention will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings, in which:

' Fig. 1 is a perspective view of a preferred embodiment of the present invention, showing the rod to which the cable holding device is to be attached;

Fig. 2 is a longitudinal sectional view of a cable holding device according to the present invention; and

Fig. 3 is a cross-sectional view on line 3-3 in Fig. 2.

Referring now to the drawing, the cable holding device comprises a cable holding member 1 consisting of two cable holding end portions la and a connecting handle portion 10 which is formed with recesses 10a permitting gripping of the handle portion.

Two pairs of clamping Springs 2, 3 serve as attaching means for attaching the device to the rod or tube 6. In the illustrated embodiment the clamping springs 2, 3 engage the rod 6, abut against the shoulders 8, 9 of the coupling sleeve 7, and hold the device in proper position with respect to the coupling sleeve 7. It will be understood that the rod consists of a great number of sections connected by a plurality of coupling sleeves, of which only one is shown.

Each cable holding portion la has an arcuate concave face lb co-operating with the rod 6, while the handle portion 10 has an arcuate concave face 10b co-operating with the coupling sleeve 7.

Each cable holding portion la has a transverse shoulder le. The confronting shoulders lc cooperate with the opposite shoulders 8, 9 formed by the coupling sleeve 7 on the rod 6. V

A'groove 4 extends in a longitudinal direction through faces lb and 10b and the shoulders le, and is adapted to receive a cable 5 which is vertically suspended adjacent the rod 6, as shown.

The device is operated in the following manner:

When the cable holding device, with a cable placed in the groove portions in the faces lb, is pressed against the rod 6 and the coupling sleeve 7, the cable is bent by the cable bending edges and forced into the aligned grooves on the transverse faces and on the guiding face 10b of the handle portion while the clamping Springs 2, 3 snap onto the rod 6.

The outwardly located portions le and 10c of the holding portions la and of the handle portion 10, respectively, are tapered and rounded so that the device can be easily inserted 'into a well.

lt Will be apparent that the clamping springs 2 and 3 serve for holding the device on the rod and need not supply pressure for holding the cable in frictional engagement with the probing rod. The cable is only supported by its bent portions 5a which abut on the annular transverse faces 8, 9 of the coupling sleeve 7. During attachment of the cable holding device of the present invention, a slight pressure is suflicient for bending the cable into its deformed shape, and for attaching the clamping Springs to the rod. An axial sliding of the device is prevented by the clamping Springs 2 and 3 which abut against the transverse annular faces 8 and 9 of the coupling sleeve so that the guiding faces 1c need not tightly engage the shoulders 8, 9.

While the invention has been illustrated and described' as embodied in a cable holding device for bending a cable in such manner that the bent cable portion abuts on a transverse shoulder of a coupling sleeve and supports the cable, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.
